Forney DURAFire - Manual

Product Overview Features & Benefits
DURAFire® Oil Igniter
The DURAFire® can be used as a Class 1, Class 2, or Class 3 igniter,
depending on the burner capacity. The DURAFire® is easily installed as a retrofit
into most burner types based on its size, capacity, and reliable operation.
The DURAFire® oil igniter consists of five major components: a guide
tube, an atomizer/head assembly, an oil/air mixture transport tube, a spark rod,
and a stainless steel diffuser for pilot stabilization. The guide tube houses the
internals, which are attached to the head and easily removed from the guide
tube for maintenance purposes by releasing a “V” band retainer, requiring no
tools. Cooling/combustion airflow is directed down the guide tube to support
and maintain the primary combustion zone during operation. This controlled
mixture of fuel and air in the primary combustion zone results in a highly
reliable, stable igniter flame. While out of service, airflow cools the igniter and
prevents debris from entering the end of the guide tube.
The DURAFire® oil igniter comes standard with Forney’s High Energy
Spark Igniter (HESI) as the spark source. The HESI produces a powerful 12-
joule spark approximately three times per second at the primary combustion
zone. The HESI spark tip is a nonfouling, surface-gap tip which is replaceable as
a unit by a threaded connection. The remaining HESI components consist of a
positioning rod, cable and power unit. Optional equipment for the DURAFire®
includes mounting hardware, retraction assembly, hoses and flame detector.
The DURAFire® oil igniter delivers the
most reliable source of energy for main
flame ignition, flame stabilization, and
boiler warm-up.
